Features
The DFF-3D Multi Beam Sonar provides high definition images of underwater conditions and the
seabed. Connected to the NavNet TZtouch/NavNet TZtouch2 Multi Function Display, the DFF-3D
distributes images of the undersea throughout the NavNet network, via LAN.
The main features of the DFF-3D are as follows.
• TX beam detects undersea conditions 120° in port and starboard directions.
• The motion sensor, provided standard, stabilizes the display to give clear and stable images
even under rough sea conditions.

1.2How to Install the Sonar
This sonar can be installed on a deck or on a bulkhead. When selecting a mounting
location, keep the following points in mind:
• Install the unit indoors.
• The operating temperature range of this unit is -15°C to 55°C (-27°F to 99°F). Be
sure the mounting location satisfies this requirement.
• Locate the unit away from exhaust pipes and vents.
• The mounting location should be well ventilated.
• Mount the unit where shock and vibration are minimal.
• Keep the unit away from electromagnetic field-generating equipment such as motors and generators.
• Observe the minimum recommended maintenance space shown in the outline
drawing at the back of this manual. Also, leave slack in cables for maintenance and
servicing ease.
• A magnetic compass may receive interference if it is placed too close to this unit.
Observe the compass safe distances noted in the safety instructions to prevent interference to the magnetic compass.
• For mounting on a bulkhead, the connectors must face downward.

1.3Transducer
Thru-hull mount
The installation position of the transducer directly affects the performance of the transducer. For best performance, keep the following points in mind when selecting the
mounting location.
• Select a location where the influence of water flow and air bubbles is minimal.
• Select a place least influenced by engine noise.
• Do not install the transducer inboard.
• For FRP vessel, do not cover the transducer with fiberglass, to prevent damage to
the transducer if the temperature rises.
• Bottom slope angle less than 24°
The illustration below is the transducer with fairing, and was created by the Airmar

• If the equipment is connected as shown in the figure below, change the time lag settings as indicated.
• If the connection is different from those mentioned here, calculate the time lag for
each sensor and enter them accordingly, using the following formula.
Time lag = Transmission delay + Propagation delay
Transmission delay: Delay required for calculation and output by the motion sensor, heading sensor, and position sensor.
SC-30: Use 5 msec for the calculation.
PG-700: Use 50 msec for the calculation.
GP-330B: Use 50 msec for the calculation.
Propagation delay: Time required for the data to reach the DFF-3D, via repeater
and data route. For the multi function display connected by CAN bus, use 15 msec
for the calculation. If NMEA data is fed to the DFF-3D via the NMEA Data Converter
(IF-NMEA2K2), set the calculation figure according to the baud rate between the
sensor and the IF-NMEA2K2 as shown below.
38400 bps: Use 40 msec for the calculation.
4800 bps: Use 145 msec for the calculation.
For example, the sensor feeding data to the multi function display via the IFNMEA2K2 has a transmission delay of 30 msec and a baud rate of 38400 bps.
Then, the time lag would be as shown in the calculation below.
Time lag 70 msec = Transmission delay 30 msec + Propagation delay 40 msec

This chapter describes the display and operations for the Multi Beam Sonar. For basic
operations with the NavNet TZtouch multi function display, such as touch operations
and power on/off, see the Operator’s Manual for the NavNet TZtouch.
The DFF-3D has four display screens (modes), multi sounder, side scan, cross section, and 3D sounder history.
4.1Display Screens Overview
Multi-sounder display
Tap the multi-sounder display icon on the home screen to show the multi-sounder display.
The multi-sounder display operates similar to the conventional fish finder, providing information about the seabed and underwater conditions. The video display scrolls from
the right to left with the passing of time.
The echoes appearing at the right edge of the display are the latest echoes. Echoes
from individual fish, schools of fish and the seabed are shown. With the gain set properly, the distance to the seabed appears on the screen.
The gain, clutter suppressor and TVG are adjusted according to the mode selected,
auto fishing or auto cruising. Manual adjustment of those controls is also possible.
The single beam presentation displays the information detected by the downwardlooking beam. The triple beam presentation displays the information detected by the
port beam, starboard beam, and downward-looking beam.

INSTALLATION INSTRUCTIONS
WARNING
Installation of the anti-rotation bolt is mandatory!
The anti-rotation bolt holds the fairing firmly in place. Failure to install the antirotation bolt may result in the fairing rotating while the boat is underway. The
effect may be violent movement and loss of steering.
This could result in serious
injury or death to passengers and/or damage to the boat or other property.

Follow the precautions below for optimal product
performance and to reduce the risk of property damage,
personal injury, and/or death.
WARNING: A High-Performance Fairing must be installed
following the installation instructions that accompany the fairing.
WARNING: Always wear safety goggles, a dust mask, and
ear plugs when installing.
WARNING: The fairing must be installed parallel to the keel
to ensure proper boat handling.
WARNING: Do not install a fairing that has been mis-cut.
Replace it.
• Cutting the fairing at an angle greater than the maximum
allowed will cut into the transducer and/ or bolt pocket,
thus weakening the fairing.
• Do not allow any gap between the fairing and the hull that is
greater than 3mm (1/8"). When the boat is underway,
water will enter any gaps and push against the fairing with
considerable force, possibly rotating it.
WARNING: Immediately check for leaks when the boat is
placed in the water. Do not leave the boat unchecked for
more than three hours. Even a small leak may allow
considerable water to accumulate.
CAUTION: Never mount a bronze transducer in a metal hull,
because electrolytic corrosion will occur.
CAUTION: Never install a bronze transducer on a vessel
with a positive ground system.
CAUTION: Never pull, carry, or hold the transducer by the
cable as this may sever internal connections.
CAUTION: Never strike the transducer.
CAUTION: Do not over-tighten the hull nut and the nut on
the anti-rotation bolt, crushing the fairing and/ or hull.
CAUTION: The transducer and the yellow triangular plug
must be flush with the fairing for smooth water flow under the
transducer.
CAUTION: Never use solvents. Cleaner, fuel, sealant, paint,
and other products may contain solvents that can damage
plastic parts, especially the transducer’s face.
IMPORTANT: Read the instructions completely before
proceeding with the installation. These instructions supersede
any other instructions in your instrument manual if they differ.
TRANSDUCER B54
This appendix provides a copy of the installation instructions and Installation supplement for the

see the materials provided with the transducer.
Technology Corporation Transducer B54. For the latest version of these instructions,
CAUTION: Do not mount in line with or near water intake or
discharge openings or behind strakes, struts, fittings, or hull
irregularities.
• The water flowing under the hull must be smooth with a
minimum of bubbles and turbulence (especially at high speeds).
• The transducer’s face must be continuously immersed in water.
• The transducer beam must be unobstructed by the keel or
propeller shaft(s).
• Choose a location away from interference caused by power and
radiation sources such as: the propeller(s) and shaft(s), other
machinery, other echosounders, and other cables. The lower
the noise level, the higher the echosounder gain setting that
can be used.
• Choose a location with a minimum deadrise angle.
• Choose an accessible spot inside the vessel with adequate
headroom for the height of the stem and tightening the nut.
Boat Types
(see Figure 1)
• Displacement hull powerboat—Locate 1/3 of the way back
along the LWL and 150–300 mm (6– 12") off the centerline. The
starboard side of the hull where the propeller blades are moving
downward is preferred.
• Planing hull powerboat—Mount well aft near the centerline and
well inboard of the first set of lifting strakes to insure that it is in
contact with the water at high speeds. The starboard side of the
hull where the propeller blades are moving downward is preferred.
Outboard and I/O —Mount just forward and to the side of the
engine(s).
Inboard—Mount well ahead of the propeller(s) and shaft(s).
Stepped hull—Mount just ahead of the first step.
Boat capable of speeds above 25kn (29 MPH)—Review
transducer location and operating results of similar boats before
proceeding.
Installation
Cored Fiberglass Hull —Follow separate instructions on page 4.
ole Drilling: Transducer
1. Drill a 3mm or 1/8" pilot hole perpendicular to the waterline from
inside the hull (see Figure 2). If there is a rib, strut or other hull
irregularity near the selected mounting location, drill from the
outside.
the hull. Be sure to hold the drill plumb, so the hole will be
perpendicular to the water surface.
Cutting the High-Performance Fairing
CAUTION: The end of the fairing with the arrows/ triangular
recess always points forward toward the bow when installed. Be
sure to orient the fairing on the band saw, so the angle cut
matches the intended side of the hull and not the mirror image.
1. Measure the deadrise angle of the hull at the selected mounting
location using an angle finder (see Figure 2). Check to be sure
the angle does not exceed 24°.
2. Tilt the band saw table to the measured angle and secure the
cutting fence (see Figure 3). Do not exceed 24°.
3. Place the fairing on the table, so the cutting guide rests against
the fence. The end with the arrows and triangular recess will be
pointing toward you for installation on the starboard side of the
boat or away from you for installation on the port side.
4. Adjust the cutting fence, so the fairing will be cut in about two equal
parts. The section that will become the fairing must be a minimum
of 45mm (1-3/4") at its thinest dimension (see Figure 2).
5. Recheck steps 1 through 4. Then cut the fairing.
6. When the boat is underway, especially at high speeds, water
will enter any gaps and push against the fairing with
considerable force, possibly rotating it. Shape the fairing to the
hull as precisely as possible with a rasp or power tool. If there is
a gap of more than 3mm (1/8"), replace the fairing.
7. Check to be sure the transducer is flush with the fairing. If it is
recessed more than 0.5mm (1/64") inside the fairing, you may
shim the transducer or carefully file/ sand the fairing.
8. The remaining section of the fairing with the cutting guide will
be used as the backing block inside the hull. It will provide a
level surface for tightening the nuts.
Hole Drilling: Anti-rotation Bolt
To locate and drill the hole for the anti-rotation bolt, use the fairing
as a guide. This will ensure that the hole is perpendicular to the
waterline and not drilled at the angle of the hull.
1. Dry fit the transducer in the fairing. Thread the cable through the
large hole in the fairing and through the mounting hole in the hull.
Seat the transducer firmly within the recess in the fairing (see
Figure 4). Be sure the arrow on the transducer points toward the
triangular recess in the fairing.
2. Slide the transducer with the fairing in place into the mounting
hole. Using the bolt hole in the fairing as your guide, drill a 3mm
(1/8”) pilot hole through the hull for the anti-rotation bolt.
3. Using the
11mm or 7/16"
drill bit or hole saw, hold the fairing in
place and drill a hole for the anti-rotation bolt.
4. Remove the assembly and cable from the mounting hole.
5. Sand and clean the area around both holes, inside and outside,
to ensure that the sealant will adhere properly to the hull. If
there is any petroleum residue inside the hull, remove it with
either mild household detergent or a weak solvent such as
alcohol before sanding.
Bedding the Transducer
CAUTION: Be sure the surfaces to be bedded are clean and dry.
1. Remove the transducer from the fairing.
2. Apply a 2mm (1/16") thick layer of marine sealant to the surface
of the transducer that will contact the fairing and up the stem
(see Figure 4 areas in red). The sealant must extend 6mm
(1/4") higher than the combined thickness of the fairing, hull,
backing block, and hull nut. This will ensure there is marine
sealant in the threads to seal the hull and hold the hull nut
securely in place.
triangular plug
with curved
surface facing
outward
3. Apply a 2mm (1/16") thick layer of marine sealant to the
following surfaces:
• Fairing that will contact the hull
• Backing block that will contact the inside of the hull
• Hull nut that will contact the backing block
4. Thread the transducer cable through the fairing and seat the
transducer firmly within the recess. Be sure the arrow on the
transducer points toward the triangular recess in the fairing.
Installing the Transducer
1. From outside the hull, thread the transducer cable through the
mounting hole. Push the stem of the transducer (with the fairing
in place) into the mounting hole using a twisting motion to
squeeze out excess sealant (see Figure 4). Be sure the arrow
on the transducer points forward toward the bow.
NOTE: The transducer must be FLUSH with the fairing. If it is
recessed more than 0.5mm (1/64") inside the fairing, you may
shim the transducer or carefully file/ sand the fairing.
2. From inside the hull, slide the backing block onto the transducer
cable and stem, seating the backing block firmly against the
hull. Screw the hull nut in place, but do not tighten it at this time.
Bedding & Installing the Anti-rotation Bolt
CAUTION: Be sure the surfaces to be bedded are clean and dry.
1. Apply a 2mm (1/16") thick layer of marine sealant to the antirotation bolt including the flange (see Figure 4). The sealant
must be 6mm (1/4") higher than the combined thickness of the
fairing, hull, backing block, washer, and nut. This will ensure that
there is marine sealant on the threads to seal the hull and hold
the nut securely in place.
2. Apply a 2mm (1/16") thick layer of marine sealant to the side of
the washer that will contact the backing block.
3. Push the anti-rotation bolt through the fairing and the hull.
4. From inside the hull, screw the washer (sealant side down) and
the nut onto the anti-rotation bolt.
5. Use slip-joint pliers to tighten the hull nut. Then tighten the nut
on the anti-rotation bolt. Do not over-tighten, crushing the
fairing or hull.
Cored fiberglass hull —Do not over tighten, crushing the hull.
Wood hull —Allow for the wood to swell before tightening the nut.

6. Use marine sealant to half-fill the hollow in the yellow triangular
plug. Apply a 2mm (1/16") thick layer of marine sealant to the
three sides of the plug that form the triangle. The sealant will
hold the plug firmly within the fairing and fill any gap between
the anti-rotation bolt and the plug.
7. The yellow triangular plug fits one way only. Push the yellow

necessary, tap it into place with a mallet.
NOTE: If the triangular plug is slightly recessed within the
fairing, use sealant to fill the gap. The plug must be FLUSH with
the fairing for good performance.
8. When the boat is underway, especially at high speeds, water
will enter any gaps and push against the fairing with
considerable force, possibly rotating it. Fill any gaps between
the fairing and the hull with marine sealant. If there is any gap
greater than 3mm (1/8"), replace the fairing.

Remove the
smooth water flow under the transducer.
Cable Routing & Connecting
CAUTION: If the sensor came with a connector, do not remove it
to ease cable routing. If the cable must be cut and spliced, use
irmar’s splash-proof Junction Box No. 33-035 and follow the
instructions supplied. Removing the waterproof connector or
cutting the cable, except when using a water-tight junction box,
will void the sensor warranty.
1. Route the cable to the instrument being careful not to tear the
cable jacket when passing it through the bulkhead(s) and other
parts of the boat. Use grommet(s) to prevent chafing. To reduce
electrical interference, separate the transducer cable from other
electrical wiring and the engine. Coil any excess cable and
secure it in place with cable ties to prevent damage.
2. Refer to the instrument owner’s manual to connect the
transducer to the instrument.
Using the appropriate size drill bit or hole saw, cut through the
skin and most of the core from inside the hull keeping the drill
perpendicular to the hull. The core material can be very soft. Apply
only light pressure to the hole saw after cutting through the inner
skin to avoid accidentally cutting the outer skin.
4. Remove the plug of core material, so the
and the inner core of the hull is fully exposed. Sand and clean the
inner skin, core, and the outer skin around the hole.
5. Coat a hollow or solid cylinder of the correct diameter with wax and
tape it in place. Fill the gap between the cylinder and hull with
casting epoxy. After the epoxy has set, remove the cylinder.
6. Sand and clean the area around the hole, inside and outside, to
ensure that the sealant will adhere properly to the hull. If there is
any petroleum residue inside the hull, remove it with either mild
household detergent or a weak solvent, such as alcohol, before
sanding.
7. Follow the same procedure to prepare the hull for the anti-rotation
bolt. Repeat steps 2 through 6.
8. Proceed with the installation beginning with "Cutting the Fairing" on
page 2. Note that all holes are already drilled.
When the boat is placed in the water, immediately check around the
transducer for leaks. Note that very small leaks may not be readily
observed. Do not leave the boat in the water for more than 3 hours
before checking it again. If there is a small leak, there may be
considerable bilge water accumulation after 24 hours. If a leak is
observed, repeat “Bedding” and “Installing” immediately (see page 3).
Installation in a Cored Fiberglass Hull
The core (wood or foam) must be cut and sealed carefully. The
core must be protected from water seepage, and the hull must be
reinforced to prevent it from crushing under the hull nut allowing
the transducer to become loose.
CAUTION: Completely seal the hull to prevent water seeping into
the core.
1. Drill a 3mm or 1/8" pilot hole perpendicular to the waterline from
inside the hull (see Figure 5). If there is a rib, strut, or other hull
irregularity near the selected mounting location, drill from the
outside. If the hole is drilled in the wrong location, drill a second hole
in a better location. Apply masking tape to the outside of the hull
over the incorrect hole and fill it with epoxy.
2. Using the appropriate size drill bit or hole saw, cut a hole from
outside the hull through the outer skin only. Be sure to hold the drill
plumb, so the hole will be perpendicular to the water surface.
3. The optimal interior hole diameter is affected by the hull’s thickness
and deadrise angle. It must be large enough in diameter to allow
the core to be completely sealed.
Anti-fouling Paint
Surfaces exposed to salt water must be coated with anti-fouling
paint. Use water-based anti-fouling paint only. Never use ketonebased paint since ketones can attack many plastics possibly
damaging the transducer. Reapply anti-fouling paint every 6
months or at the beginning of each boating season.
Maintenance, Parts & Replacement
Cleaning
Aquatic growth can accumulate rapidly on the transducer’s face
reducing its performance within weeks. Clean the surface with a
Scotch-Brite® scour pad and mild household detergent taking
care to avoid making scratches. If the fouling is severe, lightly wet
sand with fine grade wet/dry paper.

Guidelines
CAUTION: Do not mount the transducer in line with or near water
intake or discharge openings or behind strakes, fittings, or hull
irregularities that may disturb the water flow.
CAUTION: Avoid mounting the transducer where the boat may be
supported during trailering, launching, hauling, or storage.
• For best performance, the transducer’s face must be in contact
with smooth water. To identify an area of “clean” water, observe
the flow off the transom while the boat is underway.
• Allow space above the bracket for it to release and rotate the
transducer upward.
• Mounting on the side of the transom where the propeller blades
are moving downward is preferred (see Figure 1).
• Mount the transducer as far away from the propeller as possible
while ensuring the transducer’s face remains in the water when
the boat is turning.

NOTES:
-To avoid noise interference, it is recommended that the propeller is
located outside the transducer beam coverage of 120°.
-Starboard side of hull where propeller blades are moving downward is
For the best performance, the transducer beam must be aimed
straight at the bottom. Since the transom of most boats is angled,
the bracket must compensate for it. Measure the transom angle of
the boat with an angle finder.
• Single drive —Mount a minimum of 15 cm (6") beyond the
swing radius of the propeller (see Figure 1).
• Twin drive —Mount between the drives a minimum of 15cm
(6") beyond the swing radius of the propeller.
• Trim tabs —Mount inside the trim tab, space permitting.
• Stepped transom —Mount the transducer on the lowest step
being sure there is enough space above the bracket for it to
release and rotate the transducer upward (see Figure 2).
Installation
ssembling the Transducer & Bracket
1. There are two cables. Thread each cable through the
corresponding hole in the transducer support (see Figure 3).
2. Fasten the support to the transducer using the three sockethead-cap screws and washers supplied. Tighten the screws
with the 3/16" Allen wrench supplied.
3. Attach a safety ring to one end of each pin (see Figure 4).
4. While holding the transducer assembly against the bracket, insert
a pin through the upper hole in the bracket and the support.
Slide the spacer onto the pin and push it through the remaining
hole in the support and the bracket. Attach a second safety ring.
This pin will function as a hinge when the transducer is released.
5. Slide a washer onto the remaining pin. Push it through the
lower hole in the bracket, slide it along the channel in the
support, and through the second hole in the bracket. Slide the
second washer onto the free end of the pin and attach the
second safety ring. This will function as the locking pin to hold
the transducer in the operational position when underway.
• Standard transom (12° transom angle)—The bracket is
designed for a standard 12° transom angle. No shim is needed
for this installation. If your boat is capable of speeds above
20kn (28 MPH), install the bracket with one 3° shim, taper
down. This will ensure that the transducer is in contact with the
water at high speeds.
• Using shims —The bracket is supplied with three shims; each
one has a 3° angle. Up to three shims can be combined for a
maximum of 9°. The shims are designed to mate together. Two
bosses on the face fit into recesses in the back of another shim or
the holes in the bracket.
- Transom angles greater than 12°
—Add the appropriate
number of shims with the taper up to the 12° bracket angle.
- Transom angles less than 12°
—To reduce the bracket’s
12° angle, group the appropriate number of shims with the
taper down.
• If you are unsure about using the shim(s), experiment with
the them by following the instructions “Mounting & Adjusting the
Bracket.”
Hole Drilling
CAUTION: To prevent drilling too deeply, wrap masking tape
around the bit 22mm (7/8") from the point.
NOTE: Fiberglass hull—Minimize surface cracking by running the
drill in reverse until the gelcoat is penetrated.
1. At the selected mounting location, position the assembly so the
transducer projects 3mm (1/8") below the bottom edge of the
transom (see Figure 1). Be sure any shim(s) is in place. (You
may want to tape the shim(s) to the bracket temporarily.) With
the transducer in the operational position, mark the bottom
corners of the bracket.
2. Remove the transducer assembly from the bracket by removing
the locking pin and the hinge pin (see Figure 4). Hold the
bracket with any shim(s) in place against the transom at the
marked location. Draw an “X” at 12mm (1/2") from the top and
the bottom of each slot (see Figure 6).
3. Using a 5mm, #4, or 7/32" drill bit, drill four holes 22mm (7/8")
deep at the marked locations.
CAUTION: Do not position the leading edge of the transducer
lower than the trailing edge because aeration will occur.
CAUTION: Do not position the transducer deeper in the water
than necessary to avoid increasing drag, spray, and water noise
and reducing boat speed.
CAUTION: The stainless steel bracket must be isolated from a
metal hull to prevent electrolytic corrosion. If no shim is being
used, place non-metal insulating washers between the bracket
and the metal hull.
1. Apply marine sealant to the threads of four of the hex-washerhead screws to prevent water seepage into the transom. Being
sure any shim(s) is in place, screw the bracket to the hull using
a socket wrench (see Figure 4). Do not tighten the screws at this
time.
2. Reinstall the transducer. While holding the transducer assembly
against the bracket, insert the hinge pin through the upper hole
in the bracket and the support. Slide the spacer onto the pin
and push it through the remaining hole in the support and the
bracket. Reattach the safety ring.
3. Slide a washer onto the locking pin. Push it through the lower
hole in the bracket, slide it along the channel in the support, and
through the second hole in the bracket. Slide the second
washer onto the free end of the pin and reattach the safety ring.
4. With the transducer in the operational position, Use a straight edge
to sight the underside of the transducer relative to the underside of
the hull (see Figure 5). The trailing edge of the transducer should
be 1– 6mm (1/16 –1/4") below the leading edge.
5. Using the vertical adjustment space in the bracket slots, slide the
assembly up or down until the bottom inside corner of the
transducer projections 0– 3mm (0 –1/8") below the bottom of the
hull (see Figure 1). When you are satisfied with the position of the
transducer, tighten the four bracket screws. For clear access to
the screws, remove the transducer assembly from the bracket
(see Figure 4). When reattaching, be sure to include the spacer.
Testing on the Water
1. Test the transducer at 165kHz with the engine off.
2. Become familiar with your echosounder’s performance at a
speed of 4kn (5 MPH).
3. Gradually increase the boat speed and observe the gradual
decline of performance due to turbulent water flowing under the
transducer’s face.
NOTE: As the speed increases the performance at 50kHz will
deteriorate more rapidly because more acoustic noise is
generated at low frequencies.
4. If the decline in performance is sudden (not gradual), identify
the boat speed at which the onset occurred. Return the boat to
this speed, then gradually increase speed while making
moderate turns in both directions.
5. If the performance improves while turning to the side on which the
transducer is installed, it’s position probably needs adjustment.
The transducer is probably in turbulent or aerated water.
To improve performance, try the following, one at a time,
in the order given .
a. Increase the transducer’s angle in the water. Review
“Compensating for Transom Angle: Shims” and see Figure 5.
b. Move the transducer deeper into the water in increments of
3mm (1/8") (see Figure 1).
c. Move the transducer closer to the centerline of the boat.
Fill unused screw holes with marine sealant.
6. Calibration —To match the speed shown on the display to the
actual speed of the boat, you may need to calibrate the
instrument. Refer to your instrument owner’s manual.
Stabilizing the Bracket
1. Prevent the bracket from moving out of position using the
remaining hex-washer-head screw. Drill the hole for the
stabilizing screw through the center hole of the bracket, any
shim(s), and the hull (see Figure 6).
NOTE: Draw an “X”
at 12mm (1/2") from
the top and bottom
of both slots.

2. Apply sealant to the threads of the remaining screw to prevent
water seeping into the transom.
3. Fasten the stabilizing screw into place with a socket wrench.
For clear access to the screw, remove the transducer assembly
from the bracket (see Figure 4). When reattaching the
transducer, be sure to include the spacer.
Cable Routing & Connecting
APPENDIX 4 INSTALLATION OF TRANSDUCER TM54
cable cover (2)
cable clamp (4)
CAUTION: Do not remove the connectors to ease cable routing. If
the cables must be cut and spliced, use Airmar’s splash-proof
Junction Box No. 33-035 and follow the instructions provided.
Removing the waterproof connectors or cutting the cables, except
when using a water-tight junction box, will void the sensor warranty.
Route the cables over the transom for a detachable installation.
For permanent mounting, route the cables through a drain hole or
through new holes drilled in the transom above the waterline .
1. If holes must be drilled through the transom,
well above the waterline (see Figure 7). Check for obstructions
such as trim tabs, pumps, or wiring inside the hull. Mark the
locations with a pencil. Drill each hole using a 21mm or 13/16"bit
to
accommodate the connector.
2. Route the cables over or through the transom.
3. On the outside of the hull, secure each cable against the
transom using the cable clamps supplied. For the first cable,
position one cable clamp 30cm (12") above the bracket. Mark
the mounting hole with a pencil.
4. Position the second cable clamp halfway between the first
clamp and the cable hole. Mark this mounting hole.
5. If a hole has been drilled through the transom, open the large
slot in each transom cable cover. Position a cover over the
cable where it enters the hull. Mark the two mounting holes.
6. For the second cable, repeat steps 3, 4, and 5.
7. At each of the marked locations, use a 3 mm or 1/8" bit to drill a
hole 10mm (3/8") deep.
8. Apply marine sealant to the threads of the #6 x 1/2" self-tapping
screws to prevent water from seeping into the transom. If you
have drilled holes through the transom, apply marine sealant to
the space around the cables where they pass through the
transom.
9. Position the four cable clamps and fasten them in place. If
used, push a cable cover over each cable and screw them in
place.
10.Route the cables to the instrument being careful not to tear the
cable jackets when passing it through the bulkhead(s) and
other parts of the boat. Use grommet(s) to prevent chafing. To
reduce electrical interference, separate the transducer cables
from other electrical wiring and the engine(s). Coil any excess
cable and secure it in place with cable ties to prevent damage.
11.Refer to your echosounder owner’s manual to connect the
transducer to the instrument.
When the boat is placed in the water, immediately check for
leaks around the screws and any other holes drilled in the hull.
Note that very small leaks may not be readily observed. Do not
leave the boat in the water unchecked for more than three hours.
Maintenance
Anti-fouling Paint
CAUTION: Do not paint the exposed temperature button. Doing
so will slow the sensor’s response time.
Aquatic growth can accumulate rapidly on the transducer’s face
reducing performance within weeks. Surfaces exposed to salt
water that do not interlock must be coated with anti-fouling paint.
Use water-based anti-fouling paint only. Never use ketone-based
paint, since ketones can attack many types of plastic possibly
damaging the transducer. Repaint every 6 months or at the
beginning of each boating season.
Cleaning
CAUTION: Do not use a lubricant on the bracket; grit will stick to
it, increasing friction and wear.
Clean the sensor with a Scotch-Brite® scour pad and mild
household detergent, taking care to avoid making scratches on
the transducer’s face. If the fouling is severe, lightly wet sand with
fine grade wet/ dry paper.
Transducer Replacement & Parts
